/*
 * trainr.css — styling for weeks rendered by Trainr\Render\WeekRenderer
 * (the single class rendering both athletes as of Task 19).
 *
 * Task 17, Part 2: rebuilt against corpus/Sugeily_Phase2_Week1.html's own
 * <style> block (137 rules, 15 custom properties, 14 gradients/shadows) —
 * that file is the floor this design has to clear, not the target. Same
 * warm-editorial identity (bone paper, coral/sage/gold accents, an
 * espresso-dark "north star" surface, Fraunces for display type, Hanken
 * Grotesk for everything else) carried further: deeper shadow layering,
 * a refined type scale, a numbered `.ix`/`.lapnum` badge that actually
 * renders (Task 17, Part 1 restored the data; this file restores the
 * design), and one deliberate dopamine moment — completing a set, then a
 * day — everything else stays still (see the motion block near the
 * bottom, and prefers-reduced-motion).
 *
 * Fire Stick CSS floor, same as tv.css/print.css and graded by the same
 * test (tests/Render/ViewModeTest.php): flexbox/grid, plain selectors,
 * @media/@keyframes only — no relational-parent pseudo-class, no size-query
 * at-rule, no grid-inheritance value, no nested rule blocks anywhere below
 * (the literal banned tokens are deliberately not spelled out in this
 * comment — ViewModeTest's own assertions grep the whole file, comments
 * included, so naming them here would fail the very check they describe).
